Roblox Script Generated by ScripterAI

"Make a script that changes the walk buttons. W must be D, S must be A. Change it also on the arrow keys. Show me how and where to insert this script."

-- This script should be placed in StarterPlayerScripts 
local UserInputService = game:GetService("UserInputService")
local player = game.Players.LocalPlayer
local function onKeyPress(input)
    local humanoid = player.Character and player.Character:FindFirstChild("Humanoid")
    if humanoid then
        if input.KeyCode == Enum.KeyCode.W then
            humanoid:Move(Vector3.new(1, 0, 0), true)
        elseif input.KeyCode == Enum.KeyCode.S then
            humanoid:Move(Vector3.new(-1, 0, 0), true)
        elseif input.KeyCode == Enum.KeyCode.Up then
            humanoid:Move(Vector3.new(1, 0, 0), true)
        elseif input.KeyCode == Enum.KeyCode.Down then
            humanoid:Move(Vector3.new(-1, 0, 0), true)
        end
    end
end
UserInputService.InputBegan:Connect(onKeyPress)

-- Please note that this script will only work when the player's character is spawned and the Humanoid object is present in the character model. Also, this script will not disable the default movement controls, it will just add additional controls. To disable the default controls, you would need to use the UserInputService's 'StartMoving' and 'StopMoving' events.
